MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 619,853, dated February21, 1899.

Application filed September 8, 1893- Serial No. 690,487. (No model.)

To all whom it may concern:

Be it known that I, J OSEPH S. WEBSTER, a citizen of the United States,residing at Herndon, in the county of Fairfax and State of Virginia,have invented certain new and useful Improvements in Music-Leaf Turners;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention is a music-leaf turner; and it consists in the novelconstruction and arrangement of its several parts,as set out in thefollowing specification and claims thereunto attached.

In the accompanying drawings, Figure 1 is a perspective View of mycomplete device. Fig. 2 is a horizontal section on the line X X of Fig.3. Fig. 3 is a detail cross-section. Fig. 4 is a detail horizontalsection showing one of the dogs that operates one of the leafturningarms. Fig. 5 is a perspective View of one of the leaf-turningarms,showing a sliding clamp which holds one of the leaves. Fig. 6 is ahorizontal section of a modification of my device. Fig. 7 is a detailplan View of my lever rod and bar used in the modified form of mydevice. Fig. 8 is an end elevation of the same. Fig. 9 is a detailcross-section on the line Y Y, Fig. 6. Fig. 10 is a perspective view ofthe parts 18, 19, and 20 and of part of plate 22, shown in Fig. 4.

My invention is applicable to either a piano or organ, and may be alsoused in connection with music-stands,and is described as follows:

1 represents part of a keyboard of an organ. This music-leaf turner sitsin front of and against the music-rack, and the leverbar 2 hangs justover the keys in easy reach of the performer.

3 represents the lower Wall of a trough A, 4 represents the back wall ofthe trough, and 5 represents the upper wall thereof. To the back wall 4of this trough are secured two upright posts 6 and a central board 7,and to the upper ends of these posts 6 and this central board 7 is across-beam 8. To the front edge or face of the upper wall 5 of thetrough A and immediately in front of the posts 6 are secured braces 9,and just behind these braces are springs 10, their upper ends beingsecured In using music-books or bound pieces of music their backs areput between the holders 11 when turned back and the boards and leavesnot to be used are put between the braces 9 and springs 10, while theleaves to be turned are secured in the clamps 13 on the arms 14. Theholders 11 may be made telescopic, so as not to take up much room whennot in use.

The arms 14 are all pivoted on one central pin 15, (see Fig. 4,) setvertically on the upper face of the wall 3 of the trough A. The confinedends 16 of the arms 14 embrace said central pin and terminate in eyes17, and to these eyes 17 are pivoted links 18, their other ends beingeach pivoted to one end of as many levers 19. Said levers 19 are pivotedon a pin 20, and the other ends of these levers 19 operate againstsprings 21. When the arms 14 are thrown to the right, as shown in Figs.1, 2, and 5, they are a little beyond the deadcenter and remain in thatposition until operated by the dog 24, and when thrown to the left theyare held in that position by the springs 21. These arms are pivotedbetween bearings or guide-plates 22, (see Figs. 1, 3, and 9,) and on topof the upper guide-plate 22 (see Fig. 2) is pivoted a plate 23, bearingthe dog 24. This plate 23 and dog 24 are operated by clamp 25, clampedon the bend 26 of the leverrod 27, which works in bearings 28 and isprovided with elbow extensions 29, pendent rods 30, and sleeves 31, andto the said sleeves 31 is secured bar 2. The lever-rod 27 used inconnection with my modification, Fig. 6, has elbow extensions 29, curvedconnections 30', and pendent sleeves 31', (see Figs. 7 and 8,) and tothe lower ends of the pendent pieces is secured the lever-bar 2, so thatsaid bar may be adj usted inwardly, outwardly, upwardly, or down wardly,as desired; but the lastmentioned connections 29 3 '31 maybe used withmy invention, as shown in Fig. 1. On the other ends of the arms 14 areattached sliding clamps 13, so that they may be adjusted to any size ofmusic or will slide and adjust themselves while the music is beingturned in case the music has not been put in with its back on a linewith the central pin 15.

The lever-rod 27 as shown in Figs. 6 and 7 is the same as shown in Figs.1 and 2 except instead of using a bend 26 I use an upright 32, whichpasses through slots 33 in the bearings or guide-plates 22 and contactagainst one end of the pivoted plate 23, and thus operates the dog 21.This dog 24: is made of a piece of wire and is pivoted in one end of theplate 23, so as to be rigid in its right and left movements, but free torise and fall, and as it pushes off each arm beyond the dead-center andthe arm is forced to the left by its spring 21 it falls of its ownweight to catch the next arm, and so on until all the arms are thrown tothe left.

In the drawings, Fig. 1, only five arms are shown; but there may be asfew or as many arms as desired. Each trip of the bar throws one arm, andconsequently one leaf.

On the left-hand ends of Figs. 2 and 6 is seen a device 31 for givingmore or less tension to the springs 21, and therefore more or less quickand decided action to the arms 11. To lessen the tension, I move thedevice 31 to the left. To increase the tension, I move the device to theright. This device maybe moved by the hand or a screw may be used tooperate it.

Among the many advantages of my invention I call special attention,first, to the deadcenter arrangement of the arms ll; second, to thesliding clamps 13; third, to the leafholders 11 11; fourth, braces 9 andsprings 10 for holding book open; fifth, operatinglever 27 and bar 2;sixth, device 34: for lessening or increasing the tension of the springs21.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. Amusic-leaf turner consisting of aframe, composed of the posts 6,board 7, and crossbeam 8 leaf-holders 11, hinged to said board; clamp12, adapted to hold said leaf-holders together; braces 9, secured to thefront face of the trough A; springs 10, secured to posts 6, their springends contacting against braces 9; perforated guides 22, secured in thecenter of trough A; pin 15,working through the front perforations insaid guides; arms 1e, having one end working around said pin andterminating in eyes 17; links 18, one end pivoted to the eyes 1'7, andtheir other ends to the levers 19; levers 19, pivoted on a pin 20 andoperated by springs 21; dog 2i secured in pivoted plate 23; bar 2, andlever 27 and clamp 25, operating said plate and dog; sliding clamps 13,working on the free ends of levers 1i, and tension device 24,substantially as shown and described and for the purposes set forth.

2. In a music-leaf turner substantially as shown and described, theguides 22, the arms 14, pivoted between said guides, springs 21; levers19 and links 18, uniting the levers and arms and lying normally slightlyout of line with but pressing cndwise against the pivots of the arms,thereby causing the said arms to stand to the right when passed to theright beyond the dead-center, substantially as shown.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH S. IVEBSTER.
